A thermally-conductive pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer containing thermally-conductive particles. One side of the sheet is an adhesive face, and the other side is a non-adhesive face. The thermally-conductive pressure-sensitive adhesive sheet may include a non-adhesive layer on or over only one side of the pressure-sensitive adhesive layer. In this case, the ratio of the thickness of the non-adhesive layer to the thickness of the pressure-sensitive adhesive layer is preferably 0.04 to 0.6. The thermally-conductive pressure sensitive adhesive sheet preferably has a thermal resistance of 6 K·cm2/W or less. The thermally-conductive pressure sensitive adhesive sheet preferably has a total thickness of 50 to 500 μm.
